4、oreword IS0 (the international Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a te
5、chnical committee has been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member
6、bodies for approval before their acceptance as International Standards by the IS0 Council. They are approved in accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting. International Standard IS0 8391/2 was prepared by Technical Committee ISO/TC 166, Ceramic ware,

9、NTERNATIONAL STANDARD IS0 6391/2-1966 (E) Ceramic cookware in contact with food - Release of lead and cadmium - Part 2 : Permissible limits 0 Introduction The problems of lead and cadmium release from cookware require effective means of control to ensure the protection of the population against a po
10、ssible health hazard. This potential arises when improperly formulated, applied or fired glazes are applied to cookware. There is a particular concern for cookware because the normal conditions of use (heating acid foods for prolonged periods) are conducive to the extraction of soluble lead and cadm
11、ium into food. As a secondary consideration, the varying standards for cookware that exist from country to country present non-tariff barriers to international trade. Accordingly, there is a need to establish internationally accepted methods of testing cookware for lead and cadmium release, and to d
12、efine permissible limits for the extraction of these toxic metals. An expert panel convened by the World Health Organization (WHO) met (with IS0 participation) in Geneva, in November 1979, and recommended limits for the release of toxic materials from ceramic cookware for a proposed hot test method.
13、 Further, the meeting directed that the proposed method be further studied to determine its repeatability and reproducibility. The method specified in this part of IS0 8991 is based on the WHO recommendations and subsequent collaborative studies in which 14 laboratories throughout the USA, Europe an
14、d Japan participated. As the capability of the industry increases, efforts will be made to reduce these limits for lead and cadmium release. IS0 8391 consists of the following parts : Part 1 : Method of test. Part 2 : Permissible limits. 1 Scope This part of IS0 8391 specifies the permissible limits
15、 for the release of lead and cadmium by ceramic cookware intended for use in contact with food. 2 Field of application This part of IS0 8991 is applicable to ceramic cookware intended to be used for the preparation of foods by heating, 3 Reference IS0 8991 II, Ceramic cookware in contact with food -
16、 Release of lead and cadmium - Part 1 : Method of test. 4 Definition For the purpose of this part of IS0 8391, the following definition applies. ceramic cookware : Ceramic articles which are intended to be heated in the preparation of foodstuffs, for example china, porcelain and earthenware, but exc
17、ludes glass, glass ceramic and porcelain enamel articles. 5 Permissible limits The permissible limits for lead and cadmium release from any individual article, when determined by the method specified in IS0 8991/l, shall not exceed the values given in the table.
